Grid Tie Solar System | The grand solar battery

One of the prime reasons that solar has become an affordable source of renewable energy is the concept of grid-tie solar systems. Where once the major costs of installing a solar system was the cost of batteries, grid-tie systems use the utility grid as a store of energy. In the day time the solar energy is fed to the grid and the homeowner is paid for this solar power. During the night time the homeowner uses the power generated by the utility company.
